How can I recreate this lighting?
1) With Blender (Cycles Render) and Photoshop you can do it this way:


Create your object.
Create a plane under your object. Keep this plane selected. In the Properties panel > Object > Cycles Settings, enable Shadow Catcher.
In the Properties panel > Render > Output > Choose PNG and RGBA so that you can have a transparent channel, and in Film > enable Transparent.
In the Properties panel > Render > click Render.
Open your image with Photoshop, you have a PNG file with transparency and there is a shadow under your object.
In Photoshop, put a white layer under the object layer.


2) As Risingfall says, if you know how the Compositing works, you won't need Photoshop, just use a white background and an Alpha Over node.

3) A more basic solution is to play in your 3D scene with a structure of planes that either have Diffuse shader so that they can receive shadow, or Emission shader, so that they stay 100% white.
